In old times the ‘Scots’—as the Irish were then called—were well known for their warlike qualities, and very much dreaded; so that fabulous rumours regarding them ran among some of the people of the Continent. One Latin writer tells us that Irish mothers were wont to present the first food on the point of a sword to their newly-born male infants, as a sort of dedication to war. This is certainly an invention, for it is not mentioned in our own records; but it indicates the character the Irish people had earned for themselves abroad. They fought a great deal too much among themselves at home; but in this respect they were not a bit worse than the English people at the time of the Heptarchy or than the Continental nations of the same period.
That the old Irish should be warlike is only what we might expect; seeing that they were in great measure descended from the Continental Gauls, who in ancient times were renowned as warriors and conquerors. But mighty as the Gauls were, and though they were at least as brave as the Romans, they were subdued in the end by superior discipline, when Julius Cæsar invaded them. And so with the old Irish. Though they were fierce and strong, and taken man for man quite a match for the Anglo-Normans, they were forced, after a long struggle, to yield to science, skill, and discipline, when they were invaded by that people—then the greatest warriors in the world.
The Irish were not content with fighting at home, but made themselves formidable in foreign lands. Their chief foreign conquests were in Wales and Scotland; but they frequently found their way to the Continent. Irish literature of every kind abounds in records of foreign raids, invasions, and inter-marriages; and in many particulars these native accounts are borne out by authorities that no one questions, namely, Roman classical writers, whenever they find occasion to touch on these matters.
Those who have read the early history of England will remember that the Picts and Scots, marching southwards from the Scottish Highlands, gave much trouble, year after year, for a long period, to the Romans and Britons. The Picts were the people of Scotland at the time; and the Scots were the Irish, who, crossing over to Alban or Scotland in their curragh fleets, joined the Picts in their formidable raids southwards. We know all this, not only from our own native historians, but also from Roman writers, who tell us how the Romans had often to fight in Britain against the Scots from Ireland.
In order to protect the British people against these two fierce nations, the Romans, at different intervals in the second and third centuries, built great walls or ramparts from sea to sea, between Britain and Alban, of which the ruins are still to be seen: one beginning at the Frith of Clyde and another at the Solway Frith.
For several hundred years—from the third to the sixth century, and even after—the Irish streamed continually to Scotland across the narrow sea. The first of these migrations of which we have reliable accounts originated in a famine, exactly as the great exodus of our own day from Ireland to America was set going by the terrible famine of 1847. And this migration is related partly by old Irish writers, and partly by the great English historian, the Venerable Bede.
The famine in question fell on Munster early in the third century, so that numbers of people were forced to leave the province. One particular chief led a great host of fighting men, with their families, northwards, till they reached the extreme district now known as the county Antrim. Here they divided: and while one part remained in Ireland (i.e., in Antrim), the other part, under the same leader mentioned above, crossed over to Alban or Scotland, where they settled down. From this time forward, there was a continual migration, year after year, from the northern coast to Scotland, till, after the lapse of about three centuries, occurred the greatest invasion of all, led by the three brothers, Fergus, Angus, and Lorne, in the year 503.
It has been already related in our Histories of Ireland, and need not be repeated in detail here, how these colonists ultimately mastered the country, over which their first king, Fergus, ruled; how they gave Scotland its name; how the subsequent kings of Scotland were the direct descendants of Fergus; and how from him again, through the Stuarts, descend, in one of their lines of pedigree, our present royal family.
At about the same period the Irish mastered and peopled the Isle of Man; and for centuries there was constant intercourse between the parent people of the north-east coast of Ireland and this little colony. Though the Norsemen wrested the sovereignty of the island from them in the ninth century, they did not succeed in displacing either the Gaelic people or their language. The best possible proof that the Irish colonised and held possession of Man for ages is the fact that the Manx language is nothing more than Irish Gaelic, slightly changed by lapse of time. There are also still to be seen all over the island Irish buildings and monuments, mixed up, however, with many of Norse origin; and the great majority of both the place-names and the native family-names are Gaelic.
In our old historical books we have accounts of migrations of Irish people to Wales, some as invaders intending to return, some as colonists purposing to settle and remain. At this time the Romans were masters of England and Wales, but they were not as mighty a people in the fourth century as they had been previously; for on the Continent the northern barbarians were pressing on them everywhere; and in Britain the Picts and Scots, as we have said, kept continually harassing them from the north.
